Description

With the Lobaro level probe, liquid levels can be transmitted wirelessly to the Internet via LoRaWAN or NB-IoT. With the help of ceramic pressure sensors with integrated pressure compensation line, level monitoring can be realized with an accuracy of up to centimeters. For example, the 0..1.5 bar sensor of the Lobaro std. level probe is ideally suited for level detection of liquids with a depth of up to 15 meters. For applications with increased accuracy requirements, the device can alternatively be equipped with a PR26X Modbus probe of the brand manufacturer KELLER Druckmesstechnik AG can be ordered.
